Characterization of chromospheric activity based on Sun-as-a-star spectral and disk-resolved activity indices
Ekaterina Dineva, Jeniveve Pearson, Ilia Ilyin +4
The strong chromospheric absorption lines Ca H & K are tightly connected to stellar surface magnetic fields. Only for the Sun, spectral activity indices can be related to evolving…
Solar Hα excess during Solar Cycle 24 from full-disk filtergrams of the Chromospheric Telescope
A. Diercke, C. Kuckein, P. W. Cauley +4
The chromospheric H-alpha spectral line is a strong line in the spectrum of the Sun and other stars. In the stellar regime, this spectral line is already used as a powerful tracer…
Multiple Stokes I inversions to infer magnetic fields in the spectral range around Cr I 5782 Å
C. Kuckein, H. Balthasar, C. Quintero Noda +8
The spectral window, containing Fraunhofer lines formed in the solar photosphere, around the magnetically sensitive Cr I lines at 5780.9, 5781.1, 5781.7, 5783.0, and 5783.8 Å, with…
Filigree in the Surroundings of Polar Crown and High-Latitude Filaments
A. Diercke, C. Kuckein, M. Verma +1
High-resolution observations of polar crown and high-latitude filaments are scarce. We present a unique sample of such filaments observed in high-resolution H narrow-band filter…
Classification of High-resolution Solar Hα Spectra using t-distributed Stochastic Neighbor Embedding
Meetu Verma, Gal Matijevič, Carsten Denker +7
The Hα spectral line is a well-studied absorption line revealing properties of the highly structured and dynamic solar chromosphere. Typical features with distinct spectral signatu…
Observational study of chromospheric heating by acoustic waves
V. Abbasvand, M. Sobotka, M. Švanda +9
Aims. To investigate the role of acoustic and magneto-acoustic waves in heating the solar chromosphere, observations in strong chromospheric lines are analyzed by comparing the dep…
